Thank you sir for great quality content

Thank u so much sir for everything. Thank u 🌹🌹🌹❤😊

I m enjoying learning due to sir.... Thank you so much sir

[@shuvranshuhalder6623]

If u understood this, then please tell me if the swap() satisfies all 3 conditions or not. I am confused bcz it is not satisfying mutually exclusive one. Then how it becomes a feasible solution of critical section problem?

[@phanishsahu9802]

Sir key is local variable in swap implementation, so each process have their own key that remain unchanged , thus it satisfies mutual exclusion in all ways

[@boedickson5549]

lock=True statement after the loop in swap() based hardware synchronization is unnecessary, as lock will become true anyway.

[@boedickson5549]

key=True is not required, as key is made true at the very beginning, and after getting out of the while loop, key is not required.

Thank you so much sir

[@subhojitdaw5054]

Is bounded waiting and progress satisfied for this hardware critical problem solutions!?

Bhai ye video ka sequence kaise badal gaya...

[@RAJABABU-pv8ft]

Sir pls tell m testnset m cs s exit hone k baad n lock false hone s phle interrpt aa skta h kya bcoz atomic toh sirf testnset() h na

[@aanisaali48]

Yes, it can be interrupted but not preempted @RAJA BABU

[@gamerknight1615]

yes a sakta hai

[@AshishSinwer-o7e]

yes it can, preemption can also happen , but mutual exclusion will also be satisfied
